(Cl. 118-33) Thepresent invention relates to a textile treating process and apparatus.

In the tretament of certain textiles, a band of textile iibers istreated in a sizing bath or the like by being moved therethrough, and itis customary to compress the bers before they are submerged in the bath.However, the desired results are not always obtained because the fiberscontact the open air after being compressed and before being submergedin the bath. Furthermore, it is often desired to compress the fibersafter being treated in the liquid bath, but here again the contact ofthe fibers with air detracts from the desired results. Also, it isgenerally very difficult to properly regulate the force with which thefibers are compressed.

One of the objects of the present invention is to provide a process andapparatus overcoming the above drawbacks by compressing textile fiberstwice both before and after the textile fibers are treated in a liquidbath and without allowing the textile fibers to contact the outeratmosphere.

Also, it is an object of the present invention to regulate the forcewith which the libers are compressed in a fully automatic manner.

In addition, it is an object of the present invention to regulate thedriving of compression rollers in accordance with the effect of theliquid bath on the bers and in a fully automatic manner.

Further, it is an object of the present invention to provide a means foradjusting one of each of two pairs of compression rollers in such amanner that the adjustment ofy one roller is dilerent from theadjustment of the other l roller.

With the above objects in view mainly consists of a textile treatingapparatus which includes a tank adapted to have a liquid textiletreating medium therein. Two rst compression rollers are turnablymounted above a tank; these rollers are spaced from each other andextend at least partly into the tank, and thereby into the bath composedof said liquid medium. Two second compression rollers are located in thespace between said iirst rollers so that each of the second rollers isin a position adjacent to and parallel with one of the first rollers,respectively, and so that the second rollers also extend at least partlyinto the tank and into the bath therein. An adjustment means isoperatively connected to the second rollers for adjusting the positionthereof with respect to the first rollers, respectively.

The novel features which are considered as characteristic for theinvention are set forth in particular in the appended claims. Theinvention itself, however, both as to its construction and its method ofoperation, together with additional objects and advantages thereof, willbe best understood from the following description of specificembodiments when read in connection with the accompanying drawings, inwhich:

Fig. l illustrates diagrammatically one embodiment of the invention inpartly sectional elevation, the front wall of the machine frame beingomitted, the section being the present invention 2,884,893 Patented May5, 1959 taken along line I-I of Fig. 1b; Fig. 1a illustrates the drivemeans for the rollers of Fig. 1 in a fragmentary plan view; Fig. 1b is adiagrammatic partial end view of the embodiment of Fig. 1, partlysectional along line lb--Ib thereof; Fig. 2 illustrates in a partlysectional diagrammatic elevation a different embodiment, the sectionbeing taken along line II-lI of Fig. 2a, the front wall of the machineframe being omitted and also the roller drive means being omitted fromFig. 2 inasmuch as it is the same as that of Fig. 1; and Fig. 2a is apartial diagrammatic end view of the embodiment of Fig. 2, partlysectioned along line IIa-lla thereof.

Referring now to the drawings, it will be seen that within a frame A atank 1 is provided to hold a bath of liquid treating medium such as asizing liquid. Two substantially horizontal compression rollers 2 and 3are turnably mounted above the tank 1 and are spaced from each otherwhile extending across the tank 1 between two of its walls. The rollers2 and 3 are mounted for rotation about horizontal or substantiallyhorizontal axes which are substantially parallel with each other. Thebearings 2 and 3 for the rollers 2 and 3, respectively, may be mounteddirectly on the walls of the tank or, as illustrated, on a lower portionA" of frame A which is connected to the tank.

Two other compression rollers 4 and 5 respectively cooperate with thecompression rollers 2 and 3, the rollers 2, 4 forming one cooperatingpair of compression rollers while the rollers 3, 5 form the second pairof cooperating compression rollers. In the embodiment of Figs. l, la, lbthe rollers 4 and 5 are interconnected by arms 6 and 7 of a togglelinkage. A bar 10 is pivotally connected at the junction of arms 6 and7. As is apparent from Fig. 1, a spring 11 is interposed between the bar10 and an actuating mechanism comprising a hydraulic or pneumatic system15, 16, made up of cylinder 16 and a piston 15 connected with a suitablesource of iiuid under pressure so as to actuate the bar 10, piston 15being connected to the bar 10 as shown in Fig. l. A second hydraulicsystem 17, 18 in the form of a cylinder 18 and piston 17 may beconnected to the first system 15, 16, as by having the piston 17provided with a duct 17' for forcing pressure fluid through theperforated end of cylinder 16. This arrangement is of particularadvantage when several iniluencing factors are used to actuate thelinkage 6, 7.

As can be seen from Fig. l, whenever pressure is exerted by piston 15and rod 10 on the joint between the toggle arms 6 and 7, the linkageacts to move the rollers 4 and 5, with their bearings 4 and 5',respectively, sliding on the supporting walls of the tank or of theframe portion A", as illustrated, away from each other and against thecorresponding rollers 2 and 3, respectively, and to compress bermaterial F passing between the cooperating pairs of rollers, asdescribed further below. By reverse action of the piston 15 the rollers4 and 5 can be lifted.

The rollers 2 and 3 are respectively driven by shafts 19 and 20 fixed toand carrying these rollers. The drive may be obtained from a commondrive shaft 21, and with such an arrangement it is desirable to providea differential mechanism or the like having a rotating shaft which maybe braked, if desired, to equalize the drive between the two rollers 2and 3.

It is preferred, however, to drive the shafts 19 and 20 separately asshown in Figs. la and lb where the shaft 21 is driven by a chain 22 anda sprocket wheel 23 while the shaft 19 is driven by a bevel gear drive24, 25, a sprocket wheel 26, a chain 27, and a sprocket wheel 28. Thebevel gear 25 and sprocket wheel 26 are carried by a sleeve 25' which isfreely turnable on the shaft 21. A means for equalizing the drive ofsprocket wheels 23 and 28 is located between these sprocket wheels or adrive t means 2.9 having an adjustable transmission ratio is locatedbetween these sprocket wheels.

The regulation of the transmission ratio is derived from a tensionmeasuring device 3l) (Fig. 1) which is located between the rollers' 4and 5 within the bath and measures the tension of the band of fiberssubmerged in the treating liquid. This vertically'm'ovable measuringdevice 3@ resting on the band of fibers may have any known constructionand may be electrically, hydraulically, or pneumatically interconnectedwith the drive 29 for controlling the same, including e.g. apotentiometer Sil controlled by the device 3d and connected by wires 3d"with the drive 29 as is shown diagrammatically in Fig. l.

A roller 31 is located over the roller 2 and may be driven by thelatter. The roller 31 serves to bring the bers F to the roller 2. Asecond roller 32 cooperates with the roller 31, as shown in Fig. l.

lt will be noted that the rollers 2 and 4' define a space above theircontact line in which the treating liquid is located, and a pair ofwalls 33 may be carried by the bath against the end faces of rollers 2and 4 to laterally limit the space above their common contact area andto raise the level of the treating liquid therein, particularly to thelevel of the line of contact between rollers 2 and 31. In bothembodiments of the invention a back ller wiper 34 may be provided, asshown diagrammatically in Fig. 2. With the embodiment of Fig. 1 thematerial F to be treated moves over the roller 32, between the latterand the roller 31, around the roller 31 and to the roller 2 to becompressed between the rollers .2 and 31 and then' immediately submergedinto the treating liquid. The band of iibers F then travels through 90about the roller 2 and then is guided by the roller 4 deeper into thebath where the fibers then engage the measuring device 30 and then moveon to the roller 5 which guides the fibers up to the roller 3 whichcompresses the iibers against the roller S before the iibers contact theouter air. After compression between rollers 3 and 5 the fibers areguided away to a drying apparatus, for example. in the embodiment ofFigs. 2, 2a the roller 32 is omitted and only the rollers 31 and 2 formthe rollers for feeding the bers into the bath.

Otherwise this embodiment diifers from that of Fig. l in that therollers 4 and 5 are rotatably carried by a double-armed lever 3, 9 whichin turn is pivotally connected at 11) with the end of rod 10. This rod10 is operatively connected to an actuating mechanism 12 which isdriventhrough a worm drive 13, 14 mounted in the frame A', the wormwheel 13 being threadedly connected to a screw-threaded extension of rodguided in a cylinder 12'. The worm drive 13, 14 may be electricallydriven. As can be seen from Fig. 2, a vertical movement of rod 10downwardly due to rotation of Wheel 13 causes rollers 4 and 5 to pressagainst rollers 2 and 3, respectively, the bearing 5' of roller 5 beingcapable of sliding along the supporting wall of tank l or, asillustrated, of the frame portion A.

lf the tension of the fibers between the rollers 4 and 5' increases soas to register this increase on the device 3i), and if this increaseexceeds a predetermined limit, then the device Si) regulates the drive29 so that the ratio between the speeds of rotation of shafts 19 and 20is adjusted in such a way that the shaft 19 rotates faster or the shaftZ9 rotates slower. In this way the tension of the fibers F betweenrollers 4 and 5 is necessarily lowered. On the other hand if the tensionof the bers falls below a predetermined value the device 30 regulatesthe speeds of rotation of the shafts 19 and 20 in the opposite sense.

It will be understood that each of the elements described above, or twoor more together, may also ind a useful application in other types oftextile treating apparatus dilfering from the types described above.

While the invention has been illustrated and described as embodied inliquid textile treating apparatus, it is not if intended to be limitedto the details shown, since various modifications and structural changesmay be made without departing in any way from the spirit of the presentinvention.
